Overview Make an oversize plush game controller that actually works! Use conductive fabric and a Flora board to stitch up a capacitive touch sensing circuit. The controller acts like a computer keyboard, allowing you to play all your favorite old school games on emulator sites online. This is an all-sew project with no batteries, making it great for beginners and even kids to try. Read on to build your own! Special assistance creating this project provided by Risa Rose.

We've made a PDF pattern for constructing this plush controller. Download the tiled PDF (http://adafru.it/c5Y), print it out and tile the four pages together. We've also made available the pattern Illustrator file (http://adafru.it/c5Z) if you'd like to make any changes.

Stitch Circuit Iron a small piece of double-sided iron-on interfacing (http://adafru.it/c60) to a piece of woven conductive fabric. I like this mini iron (http://adafru.it/c61) for better control with small pieces.
Peel off the paper backing (or don't), and cut out the shapes necessary for your controller buttons refer to your pattern! You'll have four directional buttons, two option buttons, and two round action buttons.

If you haven't already, peel the backing from the interfacing and then iron the pieces of conductive fabric to some grey fuzzy fabric. Don't place them too close to the edge of your fabric, or you won't have anything to grip onto with your embroidery hoop in the next steps.

Place the Flora on the fabric, and following the pattern use a water-soluble embroidery (http://adafru.it/c62) marker to sketch the traces that will connect the Flora pads to the conductive fabric buttons. It's important that these traces are as far apart from each other as possible so they don't accidentally trigger each other's capacitive touch sensing. We've tested this particular pattern and it works great; we also made previous versions with traces closer together that did not work well, so keep that in mind if you're designing your own button layout.

Embroider connections that follow the lines you just drew, wrapping several times around the Flora pads and into the conductive fabric, then knot, seal, and cut the thread at the back. For more information about working with conductive thread, check out our Conductive © Adafruit Industries

Thread (http://adafru.it/aVx) guide. Remove the circuit from the embroidery hoop and iron out any creases.
Blot the blue traces with a damp paper towel to make it disappear.

The Code Paste the following code into the Adafruit Arduino IDE or download the code from Github (http://adafru.it/c63). For more information about programming Flora and to download the IDE, please visit the Getting Started with FLORA guide (http://adafru.it/aSZ). You'll need Modern Device's capacitive touch sensing library (http://adafru.it/c66) for Arduino. /* Example code for a Flora game controller with capacitive touch sensing!
